EQUIPMENT GALLERY
Sandvik unveiled the TH551i and
TH6631i autonomous hauling trucks.
When paired with the company's Auto-
Mine Trucking software package, the
trucks can increase haulage production
at a mine by as much as 30%, the com-
pany reported. Multi-machine control and
improved operating discipline can reduce
operating costs by as much as 50%.
The new trucks have built-in data col-
lection capabilities, ensuring all informa-
tion can be visualized at any time. Every
load is analyzed and high-speed contin-
uous production in autonomous mode
enables higher utilization and extended
equipment lifetime, Sandvik reported.
The new evolution in AutoMine Trucking is
decline haulage, which enables high-lev-
el utilization and improved productivity in
declines for underground hard rock miners
who use ramp haulage. This helps enable
several additional daily hours of haulage.

Programs Digest
Drillhole Data
Hexagon Mining unveiled Sigma, a com-
prehensive package of statistical and
geostatistical programs to analyze and
evaluate drillhole, blasthole, and model
data. The package is fully integrated with
MineSight Torque and MineSight 3D to
produce sophisticated and customizable
reports, charts and graphs.
Features include a statistical applica-
tion for univariate, bivariate and spatial
analysis of geological data; a modern and
intuitive user interface for batch creation,
viewing and editing of graphs; and global
refresh options for quick updates. Geosta-
tistical graphs feature advanced data anal-
ysis algorithms for streamlined variograph-
ical analysis. Intelligent defaults-based
analysis of the input data speeds initial
graph creation, the company reported.

Cone Crushers Get
Adjustable Stroke
All thyssenkrupp Kubria cone crushers
now come standard with an adjustable
stroke. Previously, the adjustable stroke
feature was offered on only the Kubria
150 and 210 models. This will allow op-
erators to change the stroke of the crush-
er shaft without needing to replace parts
of the eccentric drive unit. An adjustment
can be executed concurrently while re-
placing the crushing tools.
The stroke can be adjusted to change
the throughput rate and product quality,
and in response to the hardness of feed
material or power consumption require-
ments. The correct stroke setting ensures
Kubria cone crushers fi t perfectly into the
overall system, allowing for uniform mate-
rial fl ow while maintaining high through-
put and excellent product quality, the
company reported.

Hydraulic Rippers are Low
Maintenance
Xcentric Ripper International (XRI) of-
fers XR82, XR52 and XR42 hydraulic
rippers. These models are part of the
company's mining series, featuring a pat-
ented system that increases production
by 80% over the competition, the com-
pany reported. Machines in the series are
claimed to be virtually maintenance free,
water resistant and less noisy than other
digging tools. Although the mining series
uses the same basic technology as the
standard series, the mining models have
been designed to provide greater impact
force at lower frequency. The XR42 fea-
tures a hydraulic working pressure of 24
megapascals (MPa); the XR52 is rated at
28 MPa; the XR82 is rated at 30 MPa.
